A single dual channel barrier is required.
BARRIERS: KBIM2-IS-Z is
for Zener barriers, requires earthing.
Another version of the keyboard:
KBIM2-IS-G is for galvanically isolated barriers
SAFETY DESCRIPTION:
The required safety description for barriers assessed on �Entity�
concept is:
Maximum input voltage (Ui) 17 volts Maximum
input current (Ii) 310 milliamperes
Maximum input power
(Pi) 1.3 watts Maximum internal capacitance Ci) 4.7 nF
Maximum internal inductance (Li) 100mH The
barrier must also be capable of operating at frequencies up to 10kHz
Examples
of suitable barriers: KBIM2-IS-Z MTL767+ KB2-IS-G
please check.
CONNECTION: Standard DIN plug WEIGHT
: Approx 7kg (keyboard and repeater)
From the Keyboard unit
there is a 2m cable to the Isolation Barrier which is about 100x100x50mm.
Then there is about 1m to the Repeater Module which is about
120x120x30mm.
This has a double cable which lead to the
kb & mouse sockets on the computer.
Manufactured under AUSEX certification
and International EX certification.
“Intrinsically Safe” devices have been specifically developed for use in hazardous areas where an explosive mixture of air and gas or vapor is or may be present.
“Intrinsically Safe” devices are incapable
of causing an explosion in the surrounding explosive atmosphere.
This generally
involves adding protective components in series with energy storage devices.
The
purpose of the protective components is to reduce the risk of ignition due to
spark or increased surface temperature of components.
These areas typically include mining, petroleum and chemical engineering plants and factories processing and storing gases, solvents and other flammable substances.
Intrinsic
safety (IS) barriers are a core component of
an intrinsically safe solution.
Intrinsic safety barriers are devices that
limit current, voltage, & total energy delivered to a sensor or other instrument
located in a hazardous area.
Limiting the energy prevents fires & explosions
from occurring in areas with hazardous chemicals, gases or other ignitable atmospheres.
Items below described as IS are manufactured
under AUSEX certification,
and now have International EX certification. (EX
refers to Explosion Protection)
Reference information:
EX
Zone 0: Where hydrocarbons or gases are present at all times during normal operation,
EX
Zone 1: Where hydrocarbons or gases may be present during normal operation (for
a limited time),
EX Zone 2: Where hydrocarbons or gases are only
be present during abnormal operation (or for a very limited time).
